This makes me laugh:
Initial brain scanning studies used too few human subjects to ensure that real patterns in the data stood out from the noise. Matters came to a head in 2009 with a study apparently showing that pictures of humans in emotional situations could trigger neural activity in a dead Atlantic salmon. The researchers had used the fish to test that their scanner worked, but then wrote up the faux “study” to show how easy it is to get false results. “That was an important message,” says Gould van Praag. [“The replication crisis has spread through science – can it be fixed?” Claire Wilson, NewScientist (9 April 2022, paywall)]
dead Atlantic salmon, indeed. I wonder if it had a fashion sense as well.
